In the dissection room, a white shadowless lamp shines.

Under the shadowless lamp, Lao Zhang was wearing a white coat and holding a scalpel, dissecting the corpse.

When Li Dongliao entered, Tan Wan was standing not far from the dissecting table and watching quietly.

"The team came early." He quietly walked over to Tan Wan and followed her gaze towards the dissecting table.

Liu Xiaoyan's chest cavity was opened, and Lao Zhang was cutting her left lung.

Lao Zhang: "There is a large amount of fluid in the lungs, and the edema in the lungs is obvious, so it can basically be concluded that it is drowning."

Some microfibers and polyester silk threads were found in the nose and mouth of the deceased, as well as a lot of dust.

Other than that, there were no external injuries on the deceased.

A small amount of skin debris was found between the deceased's fingernails, and DNA comparison revealed that it was not the deceased's own. ”

"Is it the killer's dander?" Tan Wan continued to ask urgently, "What is microfiber?" ”

"I don't know." Lao Zhang said, "I have made a comparison in the database, but I have not found the corresponding person. ”

Immediately afterwards, Lao Zhang showed the fibers and polyester silk threads in the iron plate to Tan Wan, and at first glance, those things looked a bit like small woolen threads, they were intertwined with the damp dust, and they had to be seen carefully to see clearly.

"I will." Li Dongliao suddenly jumped out and answered for Tan Wan: "It is usually used as some cleaning cleaning tools, such as rags, which are the materials that will be used. ”

"Yes, Officer Li knows a lot!" Lao Zhang laughed.

Tan Wan turned his head sideways and cast an appreciative gaze: "I really can't see it, do you still know this?" ”

Li Dongliao was proud: "My aunt used to invest in a factory, which was to make some cleaning tools such as rags and mops, and I went there to work for her when I was a child!" ~”

Tan Wan used a clip to pull the cloud of dust and muttered, "This is strange. ”

"What's so strange, team?" Li Dongliao came up.

Tan Wan: "That's weird, Liu Xiaoyan's room is very clean, even the bathtub water when she drowned is clean and transparent, where did so much dust and floating objects come from?" ”

She stared at the dusty object, frowned slightly, and then asked, "What about the time of death, was it five or six o'clock yesterday afternoon?" ”

Due to the confession of the young couple downstairs, they said that they only heard a noise upstairs, and the time was after five o'clock.

Therefore, Tan Wan subconsciously asked whether Liu Xiaoyan's death time was between five and six o'clock.

And Lao Zhang's answer surprised her: "No, the deceased has been dead for at least 26 hours."

The time of death was between three and four a.m. the day before. ”

As soon as these words came out, not to mention that it was too late to talk, even Li Dongliao was shocked.

Especially Li Dongliao, he couldn't help but ask: "Lao Zhang, are you mistaken, how can it be three or four o'clock?" ”

Lao Zhang shook his head with a serious face: "I've been doing an autopsy for a lifetime, and I can't be mistaken." ”

The situation was chaotic for a while.

If Liu Xiaoyan died 26 hours ago, then who was arguing with the quarrel that the young couple heard? ?

Thinking of this, Li Dongliao instantly felt creepy.

The young couple said that they clearly heard the sound of Liu Xiaoyan and his son arguing, and the sound of talking lasted for a while, and both of them heard it, so it shouldn't be wrong.

But at that time, Liu Xiaoyan was clearly dead in the bathtub, so she completely overturned the confession of the young couple.

Putting aside the confessions of the young couple, there is still something that is incomprehensible.

"But......" Li Dongliao frowned, and paused before continuing, "According to what you said, Liu Xiaoyan was three o'clock in the morning the day before, so wouldn't it be that the murderer went to Liu Xiaoyan's house to kill her a few hours after killing Gao Meizi."

This is completely impossible in terms of time! ”

This is almost impossible in the eyes of outsiders, absolutely impossible!

The location of the Red Heart Orphanage is halfway up the mountain, while Liu Xiaoyan lives in a rental house in the city center.

City A is very large, and the roads are extremely cumbersome.

After killing Takamiko, the murderer drove to the city center immediately, which would take at least two and a half hours, and even longer if he took other means of transportation.

In this way, it is even more tense in terms of time to kill people quietly and leave a message.

Lao Zhang said: "By the way, there is another point, the limbs of the deceased have traces of being reshaped by hot water. ”

"What do you mean by reinvention?" Li Dongliao asked.

Lao Zhang patiently explained: "It is to change the appearance of the limbs of the deceased, and the corpse will not gradually stiffen half an hour to three hours after death. ”

Li Dongliao was confused: "Ah, why do you want to do this, isn't the dead drowning?" ”

"Lao Zhang, you want to say that the body has been carried, right?" "And the murderer just wanted to cover up the fact that the body had been transported, so he faked this illusion." ”

"That's right, I'd also prefer that corpses have been moved." Lao Zhang pointed to the arm on the left side of Liu Xiaoyan's corpse, "Look here."

Plaques on the deceased's body gathered on the deceased's knees and left arm. ”

The corpse spots are due to the cessation of blood circulation after death, and the lack of power of blood in the cardiovascular system and the accumulation of blood along the vascular network under the corpse, which is the result of the emptiness of the high blood vessels of the corpse and the congestion of the lower blood vessels of the corpse.

To put it simply, it is the attraction of blood according to gravity that forms corpse spots.

Coupled with the fact that the limbs of the corpse have been softened and adjusted, the two factors come together, which also means that the deceased was placed horizontally for a long time after death.

Soon, Tan Wan realized something: "Liu Xiaoyan's home is not the scene of the first crime. ”

There is no surveillance in front of Liu Xiaoyan's house, and one place that has been monitored recently is a convenience store opposite the building where Liu Xiaoyan lives.

It is said to be a convenience store, but it is actually a commissary.

The manager of the commissary is an old lady, and the degree of back of the ear is on the same level as the landlord's.

Li Dongliao communicated and negotiated with the other party for a long time before he came to the surveillance video of the past few days.

Tan Wan adjusted the time of the surveillance video forward a lot to speed up the viewing of the video.

If you want to transport the body, you have to use a car, but if the body is loaded in a car and enters the community, they can't distinguish it from the outside.

So, the vehicles that had entered and exited during that period of time, Tan Wan asked Li Dongliao to record the license plate numbers one by one, and she asked to check the suspicious vehicles one by one.

Suddenly, a tall silver truck came into view.

The body of the truck is labeled with the word 'Niu Lala', which is a truck used for large-scale express delivery.

Liu Xiaoyan's community gate is not spaced very well, so it is very difficult for this tall silver truck to drive into the community.

The car stuck at the door and adjusted several times before barely entering.

Li Dongliao didn't think much about it, and also recorded the license plate number of the truck.

From the beginning to the end of the surveillance video, Li Dongliao's notebook has written more and more license plate numbers, accumulating the license plate numbers of nearly 50 different cars.

Looking at the full number of license plates, Li Dongliao took a deep breath: "Big project......"
